Abstract
Disclosed is a submersible pumping system for pumping wellbore fluids. The submersible pumping system includes a motor assembly, a pump assembly connected to the motor assembly, and a shroud assembly attached to the pump assembly. The shroud assembly includes a shroud having a connection end and an intake end. The shroud assembly at least partially encloses the motor assembly and includes a sealing ring adjacent the shroud prevents the wellbore fluid from entering the shroud at the connection end. The shroud assembly also preferably includes a retaining ring that holds the sealing ring in place.
Claims5
A submersible pumping system for pumping wellbore fluid, comprising:
- a motor assembly;
- a pump assembly connected to the motor assembly;
- and
- a shroud assembly attached to the pump assembly, the shroud assembly,
- comprising:
- a shroud having a connection end and an intake end, wherein the shroud at least partially encloses the motor assembly;
- a sealing ring that prevents the wellbore fluid from entering the shroud at the connection end, wherein the sealing ring comprises a sealing aperture whereby a cable can extend through the sealing aperture to the motor assembly;
- and
- a retaining ring that holds the sealing ring in place.
A shroud assembly for use with a pump assembly and a motor assembly for use in pumping wellbore fluid, the shroud assembly comprising:
- a shroud having a connection end and an intake end, wherein the shroud at least partially encloses the motor assembly;
- a sealing ring that prevents the wellbore fluid from entering the shroud at the connection end, wherein the sealing ring comprises a sealing aperture whereby a cable can extend through the sealing aperture to the motor assembly;
- and
- a retaining ring that holds the sealing ring in place.
A downhole pumping system comprising:
- a pump intake;
- a shroud having a connection end and an intake end, wherein the connection end of the shroud is connected to the outer wall of the pump intake;
- a pump connector plate connected to the top of the pump intake
